GUS reported July CPI accelerating to 3.0%, a print that sits inside the NBP's ±1pp band around its 2.5% target but moves the wrong direction for a market still pricing further reference-rate cuts from the current 3.75% level, in place since the 5 March 2026 cut. The March projection round had CPI running above the 3.5% upper band through end-2026 before returning to the 2.5% point target only in mid-2027. A fresh acceleration to 3.0% in July does not overturn that path. But it removes any room for the July projection round, still unpublished, and flagged in bank research previews as likely to show an even higher CPI path through mid-2027, to surprise dovish.

Thursday's index move, though, was not a rates story. News flow attributes the 1.44% WIG20 decline specifically to Orlen and KGHM, and the tape corroborates a company-level explanation. Two separate block trades in KGHM printed on 13 August: 19,000 shares at 352.7 zloty, then 15,000 shares at 362 zloty, a nearly 3% price gap between the two prints inside a single session. KGHM trades on a modest P/E of 10.3 and a P/B of 1.93, with a dividend yield of just 0.4%. That profile leaves it more exposed to a single trading session's supply than a bank stock carrying a 6 to 8% yield would be.

A 1.44% WIG20 decline led by two commodity and energy names is a single-name story wearing a market-wide headline, and the bank index it sits alongside tells a different one.

That is why this desk has tracked WIG-BANKI separately from WIG20 since 1 August. The bank gauge's five-session slide, first flagged on 12 August against a still-rising WIG20, has now continued through a session where WIG20 itself finally rolled over, for reasons that have nothing to do with banks. WIG-BANKI's own 0.26% Thursday decline is roughly a fifth of WIG20's, and its five-session drop of 0.82% has not deepened materially since the prior note. PKO BP trades on a P/E of 12.6 with a 5.6% yield; Pekao on 10.3 with 7.8%. The rate-cut premise embedded in those valuations is still being tested by the same unpublished projection round, not by Thursday's KGHM and Orlen weakness.

The 12 August falsifier named two tests: whether the coming NBP projection confirms the March round's mid-2027 return-to-target path, and whether WIG-BANKI's decline reverses once the 17 August CPI final print and 18 August wages data land. Neither has been settled. The July CPI acceleration to 3.0% is a GUS flash figure already visible in the pack. The 17 August release is the final print the desk actually flagged, and it remains ahead. The reading stands, tested by nothing yet, and Thursday's real signal is that the sector's own gauge did not join a broad-market decline that was never about it.
